Relationship between Professional Music Background & Mental Problems

Findings:

  1. Responders WITH or WITHOUT professional musical background have the same distribution of intensity scores in Depression and Insomnia.

  1. Responders WITH professional musical background have higher median anxiety intensity

    • WITH: median=7; WITHOUT: median=6

  1. Responders WITHOUT professional musical background have more concentrated lower OCD intensity.

    • WITH: Q3=5; WITHOUT: Q3=4

Correlation among different Mental Problems

  • Trigger to explore: Responders may have multiple mental problems at the same time (e.g. an individual may have both anxiety and insomnia)
  • Method: Plotted a Correlation Heatmap based on the correlation matrix of 4 mental problems.

Findings:

  1. Overall: All these four mental problems show some positive overlaps with each other.
  1. In detail: Anxiety and Depression shows the strongest correlation (0.51), probably because these two disorders have similar symptoms.
  1. OCD seems to have a relatively weak correlation with other disorders. The most highly correlated problem with OCD is anxiety, as they may both be caused by stress.
